STOKING DEVICE.

SPECIFICATION forming part of Letters Patent No. 657,632, dated September 1 1, 1900. Application filed March 7, 1900. Serial No. 7,754. (No model.)

To all whom it may concern:

Be it known that I, JULIUS WEZEL, a subject of the King of Saxony, residing at Leipsic, Saxony, Germany, have invented a certain 5 new and Improved Stoking Device for Use in Connection with Boiler or other Furnaces, of which the following is a description.

The present invention consists of an improved stoking device for use in connection with boiler and other furnaces.

The invention consists of the details of construction hereinafter set forth, and particularly pointed out in the claim.

In order to render the present specification i easily intelligible, reference is had to the accompanying drawings, in which similar letters of reference denote similar parts throughout the both views.

Figure 1 is a vertical section through the front part of a boiler-grate provided with the present stoking device, and Fig. 2 is a plan of the grate in the form of a horizontal section taken along the line N of Fig. 1.

Between the slantingly.- arranged superposed sets of grate-bars a row of tubes h h is provided, said tubes being arranged one alongside the other between the grate-bar sets, so that they may form a guideway for the prongs 2 z of sets of stoking-irons s s,

0 which extend out at the front of the furnace and are provided with suitable handles. Each prong of the stokingiron extends through one tube h and the number of stoking-irons employed may correspond to the number of steps of the furnace-grate, if desired. The object of this arrangement is twofold: In the first place, irons of this class enable the fuel to be very evenlydistributed over the grate-bars of the various steps, and, in the second place, the arrangement of the tubes 77. it has the effect when the irons are Withdrawn from the hot grates of causing the feed-air to the steps to pass around the separate prongs of the stoke-irons, and thus to cool them and at the same time to forewarm the feed-air. In their position of rest the prongs of the stoke-irons lie within the tubes h h. It will be readily understood that after stoking and raking the fire the prongs will become very hot and will remain hot for a considerable time when withdrawn into the tubes h h, and thus the feed-air entering between the grates will be forced through the small hot passages formed by the difierence in size of the exterior diameter of the prongs and the interior diameter of the tubes h.

I claim as my invention- In a stoking device for furnaces, the combination with a step-grate, of a series of tubes arranged in rows between the steps thereof, and stoking-irons having a series of prongs, said prongs arranged to pass through said tubes, substantially as described.

In Witness whereof I have hereunto set my hand in presence of two witnesses.

JULIUS WEZEL.
